strtok wont end!

i cant get strtok to end! in all the examples i found it ends but mine wont! i dont see it.

heres my code

Code:

---

test("-x,-y");

int test(char options[]) {
    char *options_backup = malloc( strlen(options) + 1 );
        strcpy(options_backup, options);
    char *current = strtok (options_backup, ",");
 
    while(current != NULL) {
        printf ("%s\n", current);
       
        current = strtok(NULL, ",");
    }

    return 0;
}

That works perfectly fine here, make sureyou #include the appropriate headers.

And don't forget to free() the memory you've malloc'd
